A through hole 21 is provided in the convex portion 20. As shown in FIG. 5, the through hole 21 has a cross shape when viewed from above or below, and becomes divergent from above to below, so that the shaft portion 61 of the operating body 6 described later can be moved in the first direction and the first direction described later. It is configured so as not to obstruct the two-way reciprocating movement. An abutting support surface 22 which is a part of a spherical concave surface is provided on the upper end surface of the convex portion 20. At the edge of the lower opening of the through hole 21 on the lower surface of the upper part of the fixed guide 2, two guide grooves 23 are provided in parallel and in a straight line direction, and at a position inside the two guide grooves 23. Two guide protrusions 24 having a semicircular cross section are provided in parallel and in a straight line direction. The end face of the bottom opening of the fixed guide 2 is placed on the upper surface of the bottom 11 of the case 1, and the fixed guide 2 is fixed to the case 1.

In the figure, 3 is a slide guide. As shown in FIG. 8, the slide guide 3 has a substantially square shape when viewed from a plane, is formed by bending a rising piece 30 upwardly at a right angle on two opposite sides of the slide guide 3, and the other two opposite sides. The hanging piece 31 is bent downward at a right angle to the side. A circular through hole 32 is provided at the center of the slide guide 3. The diameter of the through hole 32 is set so that the shaft portion 61 of the operating body 6 described later can reciprocate in the first direction and the second direction described later. The rising piece 30 of the slide guide 3 is reciprocally slidably engaged with the guide groove 23 and the guide projection 24 of the fixed guide 2 to attach the slide guide 3 to the fixed guide 2. The sliding direction of the slide guide 3 is referred to as the first direction.

In the figure, 4 is a slider. The slider 4 has a hollow box shape, and an engaging hole 40 is provided at the center of the upper portion. The engagement hole 40 has a circular shape when viewed from above or below, and becomes divergent from above to below, and when the shaft portion 61 of the operation body 6 described later reciprocates in the first direction and the second direction described later. So that it does not interfere with Two guide protrusions 41 having a semicircular cross section are provided in parallel and in a straight line on the upper surface of the upper portion of the slider 4. The guide protrusion 41 of the slider 4 is engaged with the inside of the hanging piece 31 of the slide guide 3 so as to be slidable back and forth in a second direction orthogonal to the first direction, and the slider 4 is slid.

The fixed contact 51 is arranged on the upper surface of the bottom 11 of the case 1 so as to face the movable contact 50.

In the figure, 6 is an operating body. The operating body 6 includes a central spherical portion 60, a shaft portion 61 integrally projecting downward from the spherical portion 60, and a mounting portion (not shown) integrally projecting upward from the spherical portion 60. Consists of. As shown in FIG. 5, the shaft portion 61 has a substantially square cross section from the spherical portion 60 to the middle thereof, and the tip portion has a circular cross section. The spherical portion 60 of the operating body 6 is rotatably attached to the upper portion of the main body 10 of the case 1 and the abutting support surface 22 of the fixing guide 2 so as to be rotatable. Further, the shaft portion 61 of the operation body 6 is inserted through the through hole 21 of the fixed guide 2 and the through hole 32 of the slide guide 3 and is engaged with the engaging hole 40 of the slider 4. A return spring 62 and a washer 63 are interposed between the operation body 6 and the fixed guide 2, and a knob 64 as an operation portion is attached to the attachment portion of the operation body 6. In the figure, reference numeral 65 is a switch knob for two-way switching.

Thus, when the knob 64 of the operation body 6 is operated in the first direction against the spring force of the spring 62 with a finger or the like, the slider 4 moves together with the slide guide 3 as shown in FIG. Slide in the first direction (direction of arrow A in FIG. 6). Alternatively, when the knob 64 of the operation body 6 is operated in the second direction against the spring force of the spring 62 with a finger or the like, the slider 4 alone moves in the second direction (in FIG. 7) as shown in FIG. Slide in the direction of arrow B). As a result, the movable contact 50 of the slider 4 comes into contact with the fixed contact 51 of the bottom 11 of the case 1 to form a desired circuit. When a finger or the like is released from the knob 64 of the operation body 6, the slider 4 and the slide guide 3 or only the slider 4 is automatically returned to the original neutral position by the spring return force of the spring 62. Moreover, the knob 64 of the operating body 6 also automatically returns to the original neutral position. An example of this type of multidirectional switch is described in Japanese Utility Model Laid-Open No. 57-103246.
